Railway applications - Platform barrier systems

This European Standard specifies requirements for the design, construction and operation of platform barrier systems positioned at the edge of a station platform immediately adjacent to rail or other guided vehicles in stations and boarding points for passenger services and includes:
- requirements for the fixed structure and fixed parts along the platform;
- physical requirements for the movable doors and gates normally used by passengers;
- requirements for emergency doors;
- requirements for driver access doors;
- requirements for platform extremity doors;
- requirements for management of safety risks that are particular to barrier systems.
This European Standard also gives requirements for the integration of barriers with the overall rail system including:
- synchronization of vehicle and platform barrier doors or gates;
- audible and visible alerts;
- integrity of control systems;
- testing of the barrier installation;
- operational performance;
- requirements relating to other interfacing sub-systems, notably signalling and vehicles.
For barrier systems set back from the platform edge, which are used to control access to trains or for crowd management, relevant sections of the document can be used as guidance.
This European Standard applies to all actors involved in the implementation and system integration of a platform barrier system, including infrastructure owners, designers, installers and operators.
This European Standard does not cover barrier systems using bars, ropes, etc. or which operate in a vertical direction.  
This European Standard applies to light rail services, e.g. metro and tramway systems and heavy rail services as requested by a project specification. It applies to small systems, working in conjunction with a single vehicle, or with larger systems working with a complete train.
This European Standard applies to platform barrier systems used at sub-surface stations, enclosed surface stations (e.g. those enclosed for the purposes of providing an air-conditioned environment for waiting passengers), and those fully in the open-air.
This European Standard does not cover normative requirements relating to fire performance or fire requirements arising from use of platform barrier systems as fire barriers.

Introduction

Platform barrier systems provide a movable barrier between trains and other guided transit vehicles,

and passengers waiting at stations and boarding points.

Platform barrier systems are used increasingly on metro and other rail networks to ensure the safety of

passengers on the station platform who are waiting to board vehicles. Such systems are also used on

“people-mover” guided systems for short-distance transits, for example at airports. Their use is

recommended by EN 62267 for any fully automated transit system.
In particular platform barrier systems can be used to control the risk of:

• incursion by passengers or other persons on the railway track (deliberate or accidental); and

• contact between passengers and moving vehicles.

These risks can be especially significant where there is the possibility of overcrowding on station

platforms at busy locations. Barriers may increase the safely useable space in the station for passengers

waiting and circulating on the platforms.

Platform barrier systems integrate the operation of the platform barrier doors and gates with opening

and closing of train doors and also assist in the management of station operations, to safely permit higher

speeds for trains entering and exiting the stations.

Barrier installations can also be part of a continuous partition between the running tracks and the station

areas for the purposes of:
• fire safety (including smoke management);
• tunnel and station ventilation (including reduction of the piston effect);
• trackside noise reduction; and
• passenger comfort at climate-controlled stations

Additionally, the terminology used in connection with platform barrier systems, in particular to improve

the specification and understanding of safety requirements, should be standardized.

1 Scope

This document specifies requirements for the design, construction and operation of platform barrier

systems positioned at the edge of a station platform immediately adjacent to the rail or other guided

vehicles in stations and boarding points for passenger services. This document includes:

• requirements for the fixed structure and fixed parts along the platform;

• physical requirements for the movable doors and gates normally used by passengers;

• requirements for emergency doors;
• requirements for driver access doors;
• requirements for platform extremity doors; and

• requirements for the management of safety risks that are particular to barrier systems.

This document also gives requirements for the integration of barriers within the overall rail system,

including:
• synchronization of vehicle and platform barrier doors or gates;
• audible and visible alerts;
• integrity of control systems;
• testing of the barrier installation;
• operational performance; and

• requirements relating to other interfacing sub-systems, notably signalling and vehicles.

For barrier systems set back from the platform edge, which are used to control access to trains or for

crowd management, relevant sections of the document can be used as guidance.

This document applies to all persons involved in the implementation and system integration of a platform

barrier system, including infrastructure owners, designers, installers and operators.

This document does not cover barrier systems using bars, ropes, etc. or which operate in a vertical

direction.

This document applies to light rail services, e.g. metro and tramway systems and heavy rail services as

requested by a project specification. It applies to small systems, working in conjunction with a single

vehicle, or with larger systems working with a complete train.

This document applies to platform barrier systems used at sub-surface stations, enclosed surface stations

(e.g. those enclosed for the purposes of providing an air-conditioned environment for waiting

passengers), and those fully in the open-air.

This document does not cover normative requirements relating to fire performance or fire requirements

arising from use of platform barrier systems as fire barriers.

Platform barriers are also subject to aerodynamic loads induced by trains passing the structure. Platform

barrier systems installed in open sections shall also resist wind loading. In addition, platform barrier

systems might be subject to pressures generated by tunnel ventilation systems and might be required to

resist earthquakes. These separate actions shall be combined in accordance with Structural Eurocodes
